- members 24 and /25 against the periphery of lgases and burnt the valve l2 with the desired pressure for preventing the escape lof fluid pressure around the valve from the port 12 `which they surround.

The valve l2 may be operated in any suitable manner to time its rotation', and consequently the communication of the ports 17 and 18 with the port 10, for the introduce tion of charges into the cylinder 6, and the exhaust of the burnt gases therefrom, with relation to the engine-piston represented at 27, but as mechanism for this purpose in connection with rotary valves in general is commonly used and is well known in the art, a description of the valve-operating means is deemed unnecessary.

The formation of separate passages in the valve 12 with separate openings through the periphery of the valve is of advantage in an internal combustion engine as the fresh gases traverse different passages in the valve, thus avoiding intermixlture of these gases in the valve Which is very desirable. Furthermore, by so constructing the valve 12, as described, as'to cause the areaof the passage therein for the fresh, cooling, gas to be introduced into the cylinder, to be relatively great compared with the area of the ports communicating with this passage, a material cooling elfectis pro- -duced on parts described being f' the valve by the relatively cool gas which tends to prevent excessive heating of the valve with the manifest advanta es.

While I have illustrated and descri ed my improvements as embodied -in a valve of the, strictly rotary type and of spherical form and vcooperating with packing-members surrounding the port, I do not wish to be understood asintending to limit my invention to its use in such a valve as it may be incorporated in a valv'e of either the rotary or oscillatory type, whether spherical or not, and with or without packing-rings surrounding the cylinder port.

By using the word rotatory in the following claim, I wish to be understood as intending to claim broadly any valve which moves about an axis and contains. myimprovements, Whether the valve be what is commonly termed a rotary valve or an oscillatory or rocker valve.

What I claim as new and desire to secure by Letters Patent'is* iTlie combination with an internal combustion engine having a port serving for both inlet and exhaust, of a rotatory valve controlling said port and adapted to be operated in timed relation to the piston of the engine and containing passages opening through opposite ends, respectively, of said valve, a partition in said valve dividing, it into compartments opening, respectively, into the open ends of said valve, the wall of said valve containing ports opening, respectively, into said compartments and serving as inlet and exhaust passages, a hub e): tension on `said partition, and a stem for operating said valve secured in said hub.
